2 Claims.

This invention relates to certain improvements in locomotive end frames, and the object of the present invention is to so construct the end frame that a draft gear can be inserted in the cavity of the frame from the top.

In the accompanying drawing:

Fig. 1 is a plan View of an end frame having a draft gear pocket so arranged that the draft gear can be inserted from the top;

Fig. 2 is a sectional View on the line 2-2, Fig. 1;

Fig. 3 is a perspective view of the filler stop casting; and

Fig. 4 is a detached perspective view of the removable top plate.

Referring to the drawing: 1 is the end frame which may form a cylinder saddle. At the forward and of the structure is an integral bumper 5, in the present instance.

In the end frame 1 is a cavity 20, having a rearward extension 20a less in Width than the said cavity, the cavity and the extension are open at the top for the insertion of a draft gear a. The opening in the top is substantially the length of the draft gear. The bumper 5 extends over the draft gear and coupling as shown. The truck center pin guide 17 is an integral part of the casting of the end frame and acts as a support for the body of the draft gear. A removable top plate 21 extends over the cavity 20 and is secured to the frame by bolts 22. A removable filler stop casting 23 is inserted back of the draft gear and in front of the extension 20a of the cavity after the draft gear is in place. The filler stop casting 23 has stops 13a. for the rear of the draft gear.

At the forward end of the cavity are stops 13 for the front end of the draft gear. This construction allows the draft gear a. to be inserted in the casting from the top, after which the filler stop casting 23 is inserted back of the draft gear and the plate 21 secured in position. A plate 24 extends under the coupling member and is secured to the bumper. To detach the draft gear all that is necessary is to remove the top plate 21 and the detachable filler stop 23, the draft gear is then moved backwards, the rear extension of the draft gear entering the recess 20a, after which the draft gear can be raised and removed through the top opening in the frame.

By forming the end frame in the manner described, it can be made in a single casting, which will be comparatively light and of suflicient strength to stand the strain placed upon it, and yet allow the draft gear to be inserted in the cavity of the casting from the top; and when the filler stop and top plate are in place, the draft gear will be held firmly in position.

We claim:

1; The combination in a locomotive end frame having a longitudinal cavity at one end for a draft gear and having an integral center pin plate forming a portion of the bottom of the cavity; a draft gear in the cavity and resting upon the center pin plate, said cavity having an extended longitudinal top opening of substantially the same length as the draft gear; a detachable plate extending over the cavity; a removable filler stop casting normally immovably located in the cavity back of the draft gear; and means for securing the detachable plate to the frame; whereby upon removal of said plate and filler block the draft gear may be moved rearwardly and then lifted upwardly through said top opening.

2. The combination in a locomotive end frame having a longitudinal cavity at one end for a draft gear and a rearward continuation of said cavity for assisting in the removal or installing of the draft gear and having an integral center pin plate forming a portion of the bottom of the cavity; a draft gear in the cavity and resting upon the center pin plate, said cavity having an extended longitudinal top opening of substantially the same length as said draft gear; a detachable plate extending over the cavity; a removable filler stop casting normally immovably located in the cavity back of the draft gear and forward of said rearward cavity; and means for securing the detachable plate to the frame; whereby upon the removal of said plate and filler block said draft gear may be moved rearwardly into said rearward cavity and then lifted upwardly through said top opening.
